IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 39,929, dated September 15, 1863.

To all whom it may concern:

Be it known that I, G. WV. HUNT, of Muscatine, in the county of Muscatine and State of Iowa, have invented certain new and useful Improvements in Flows; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a plan or top view of my invention Fig. 2, a side sectional view of the same, taken in the line w m, Fig. 1. Fig. 3 is a transverse vertical section of the same, taken in the line y 3 Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to certain new and useful improvements on a plow for which Letters Patent were granted to me bearin g date March 27, 1860.

The invention consists, first, in a novel and improved manner of adjusting the beam of the plow, whereby the same may be kept and made to work in a horizontal position when the machine is passing over inclined ground.

The'invention consists, second, in a novel arrangement of the rod which connects the beam with the axle of the machine, whereby said rod and the front of the plow-beam may be readily raised and lowered.

The invention consists, third, in a novel and improved mode of hanging and arranging the rotary colter, whereby the same may be readily adjusted higher or lower, as may be desired, and a colter of large diameter used.

The invention consists, fourth, in a novel lubricating arrangement applied to the wheels at the back end of the plow-beam, whereby the axle of said wheels may always be keptin a proper lubricating state.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents an axle, which has a wheel, B, 011 each end of it,and a draft-pole, O,attached by joints a a.

D represents a plow-beam, and E the plow, attached thereto by bolts 1), as shown in Fig. 2. Through the front part of the beam D a vertical rod, F, passes, the upper part, c, of which is a screw, and the lower part, d, of cylindrical form, the other portion, e, which is the longest, being of square form. The lower cylindrical part, dot the rod F passes through the beam D, the latter resting on a key,f, as shown in Fig. 2.

To the under side of the axleA there is permanently secured a metal plate, G, which is provided with pendent bearings g, in which the axes h of friction-rollers H are fitted, providcd with flanges, and between which the square portion 0 of the rod F passes, said square portion 0 also passing through the axle A and between friction-rollers I I, the axes t of which have their bearings j attached to a sliding plate, J, on the upper surface of the axle A. The plate J slides longitudinally on the axle A, and is provided with longitudinal slots k it, through which screws lpassinto the axle, the screws retaining the plate in proper position.

K is a bridge, which rests upon the hearings j of the friction-rollers I I and is over the latter. The screw 0 of the rod F passes through this bridge and through a washer, m, placed thereon, and a nut, L, is fitted on the screw, said nut resting on the washer m.

At the back part of the sliding plate J there is a rack, a, into which a toothed segment, 0, gears, said segment being at the front end of a lever, M, the fulcrum-pin p of which passes through a horizontal plate, N, attached to the rear side of the axle A. The back end of the plate N is of segment form, and is perforated near said end with holes q, as shown clearly in Fig. 1.

To the upper surface of the lever M there is attached a lever, O, to the under side of the outer part of which a spring, P", is attached, said spring bearing against the upper surface of the lever M, and having a tendency to keep the inner end of lever O pressed down. The inner end of the lever O is provided with a pendent pin, r, which is fitted in any of the holes q of the plate N, the spring P having-a tendency to keep the pin r in the hole in which it is fitted. By this arrangement it will be seen that the front of the plow-beam may be adjusted either to the right or left by actuating the lever M, and-the plow E kept in a perfectly horizontal position if the axle A be inclined in consequence of the wheels B passing over inclined ground.

The lever M, it will be seen, is held by the pin 1 fitting in any one of the holes q in the plate N. .The lever M, with its toothed segment 0 gearing into the racks n, forms a very simple and convenient means for adjusting the plow-beam,the sliding plate J actuating the rod F and the latter moving the plow-beam D. The lower plate, Gr, it will be understood, is stationary.

The friction-rollers H I insure an easy movement of the rod F both under the action of the plate J and the nut L, the latter being used for raising and lowering the front end of the plow-beam.

P represents a rotary colter, which may be of steel or other suitable metal. This colter is fitted on an axle, s, the latter being below the plow-beam D and attached at one end to a vertical bar, Q, which extends up by the side of the beam D, and has two vertical oblong slots, 25 t, made in it, as indicated by the dotted lines in Fig. 2.

R is a plate at the outer side of the bar Q, and is secured thereto by a clip, S, which encompasses the beam D, the upper part of the clip passing transversely over the beam and through the upper slot, t, in the bar Q, the lower part of the clip passing transversely under the beam D and through the lower slot, t, of the bar Q. The plate It is secured on the ends of the clip byserew-nuts u u, and by means of these nuts and the oblong slots t in the bar Q the bar Q, and consequently the axle s of the colter P, may be raised or lowered, as desired. A colter, also, of any diameter, may by this arrangement be used, as the colter is at one side of the plow-beam. A large colter is a great advantage. It is not so-liable to clog up with weeds and trash as a small one, audit cuts through the weeds and trash much more readily than one small in diameter. The adjusting of the colter higher or lower is an essential feature, as the sod only requires to be cut through, and the proper depth of cut may be obtained with the greatest facility.

To the back part of the plow-beam D there is attached a vertical tube, T, the lower end of which branches out laterally at two opposite points, forming a tube, u, for the axle U of two wheels, V V, to pass through. The axle U is allowed to turn freely in the tube a, and to the upper end of said tube the drivers seatW is fitted, said seat having a pendent rod, X, attached to it, which rod is fitted in the upper end of the tube T. By this arrangementit will he seen that the axle U may at all times be kept properly lubricated by simply pouring lubricating material into the upper end of the tube T, and dust is preventedfrom entering into said tube in consequence of the upper end of the latter being covered by the seat W.

The front part of the plow-beam D may be raised temporarily at any time, when required, by means of a treadle, Y, which is attached to one side of the beam D, and is connected by a chain, a", to the under side of the axle A.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Incliniug the plowto suit the inclination of the land by the means and in the manner herein shown and described.

2. The friction-rollers H I, in combination with the sliding plate J, fixed plate G, and rod F, for the purpose specified.

3. The employment or use of the two wheels V V at the rear or back end of the beam D, when said wheels are used in combination and in relation with the plow E and drivers seat W as set forth.

4. The arrangement of the tube T, branched at its lower end to receive the axle U of the wheels V V, as and for the purpose herein set forth.
